IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 176.112, dated April11, 1876; application filed March 11, 1876.,

To all whom it may concern Be it known that I, WILLIAM T. W001), ofMount Juliet, in the county of Wilson and State of Tennessee, haveinvented a new and valuable Improvement in Lamp-Extinguisher5 and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figures 1, '2, and 3 of the drawings are representations of verticalcentral sections of my lamp-extinguisher.

The nature of my invention consists in the construction and arrangementof an extinguishing attachment for lamp-burners, as will be hereinaftermore fully set forth.-

1n the annexed drawing, A represents the ordinary collar of alamp-burner, with perforated flange or disk B, wick-tube O, and cap D,all constructed in any of the known and usual ways.

The extinguisher consists of a cap made in twoparts, G G, each havingtwo arms or projections, aat, extending down the wick-tube G, to whichthey are pivoted and allowed to fall apart by their own weight. Thelower ends of the arms a are made wide, as shown, and rest upon a plate,1), below where they are pivoted. An arm, d, extends from the plate 1)down through the perforated disk B, and the lower end of said plate isformed or provided with afoot, e. Through this foot passes a rod, f, theupper end of which passes through the disk B, and has a head, or itsequivalent, on its extreme upper end, to prevent its falling through thesame.

To the lower end of the rod f, immediately below the foot 0, is hooked abell-shaped dislr, h, with weight H suspended therefrom.

To close the extinguisher it is only necessary that the plate b beraised a little, which is accomplished by the bell-shaped disk h actingagainst the samewhen the lamp is turned at an angle from theperpendicular.

The extinguisher thus acts automatically in putting out the flame whenthe lamp is accidentally upset; and by its construction it fills nearlyall the space in thecone or flamecap D, thus causing the draft or coolair to pass between the arms of the cap, forcing its way up beside thewick-tube, driving all the heat upward, generating no gas or vaporwhatever; consequently there is nothing to cause the lamp to explodewhile at rest.

What I claim as new, and desire to secure by Letters Patent, is-

1. The bisected cap G G, each half-formed with two arms, a. a, pivotedto the wick-tube,

in combination with the plate b, weight E,

and rod (1, as and for the purpose set forth.

2. The plate I), with arm 01 and foot 6, in

combination with the cap G, arms a, rod f,

and disk h, with weight H, all substantially as and for the purpose setforth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM THOMAS WOOD.
